This template includes 2 useful rulers on the same sheet of material for helping you shape a surfboard. I suggest 0.5mm clear PETG. You are only buying the template file from me and not the actual rulers. You use the template file to create the rulers through ponokos website. Send me a message if you have any questions
The first ruler is a 12" x 24" clear flexible rectangle that is placed on the string of the board and allows you to easily mark dimensions to the rail and fin placements. There is also a cutout on the ruler to help draw the fin lines. This ruler also includes 30, 45, and 60 degree lines.
The second ruler is a 30" straight edge.
Both rulers have a hole to hang them and are laser etched. You will need to rub some black stuff into the etching so you can clearly see the markings.
Good luck and shape away.
